In this post we present 3 circuit ideas for creating beautiful Christmas tree light decorations. The first idea explains a transistorized flashing blinking LED string light which can be mounted on a Christmas tree. The second circuit diagram describes an LED light effect generator which can be also installed over a real Christmas tree for […]

220V Operated LED Flasher Circuit using Triac
The following triac/diac based mains operated LED flasher circuit which is actually an astable multivibrator circuit utilizes only a diac and resistor arrangement for implementing interesting wig wag flashing of two LEDs. The simple 220V flasher circuit was shared with me by Mr.Vineesh, who is one of the keen followers of this blog. I would […]
230 Volts Bulb String Light Circuit for Diwali and Christmas
In this article I have explained how to wire tiny 12 volt flashlight bulbs into decorative string light for decorating houses during festivals like Diwali and Christmas. What are String Lights As the name suggests a string light is a wired lamp system in which many lamps such as bulbs or LEDs are joined together […]

Learn how easy it is to build a LED wig wag string light flasher using just a couple of transistors and few other passive components. LED Flashing String Lights for Decorating Homes A LED flasher schematic has also […]
Arduino RGB Flowing Sequential Light Circuit
In this post we are going to make a simple but useful circuit that can make an RGB LED glow in a nice flowing way. That is not just random blinking, but smooth sequential lighting of red, green, and blue one by one. This is done using Arduino, so you need to have some basic […]
Sunrise Sunset Simulator LED Circuit
In this post I have explained how to make a sunrise/sunset simulator circuit using LEDs and just a couple of BJTs. The idea was requested by Mr. Jerry Circuit Objectives and Requirements The Design As proposed, a simple sunrise and sunset simulator circuit can be implemented using the circuit shown in the following diagram: The […]
